Problems solved by technology

However, in the manufacturing process, at least three components, sill, pallet and reinforcement, must be manufactured and assembled. Problems such as cumbersome, difficult, and low-efficiency search for parts, as well as the large amount of handling of each part, seriously affect the production efficiency of sill components. A total of three times of shearing and blanking, punching and

Abstract

The invention discloses a high-strength integrated bent sill. The high-strength integrated bent sill comprises a sill part provided with a sill groove, a first bent part which is connected with one side of the sill part and formed by bending, a sill supporting plate part which is connected with the first bent part, formed by bending and located below the sill part, a first sill installation part which is connected with the sill supporting plate part and formed by bending, and a second sill installation part which is connected with the other side of the sill part and is formed by bending, wherein the sill supporting plate part is connected with the sill part through a first connecting piece; the first sill installation part is connected with the second sill installation part through a second connecting piece; and a plurality of notches distributed in an extending direction of the sill groove are formed in the sill supporting plate part, and reinforcing parts formed by bending are arranged on edges of the notches. The sill is good in structural strength, low in manufacturing cost and high in manufacturing efficiency.

Description

technical field [0001] The invention relates to the field of elevator sills, in particular to a high-strength integrated bending sill. Background technique [0002] In elevator systems, traditional sill components generally include sills, supporting plates, and reinforcing ribs. The supporting plates are used to install and support the sills, and the reinforcing ribs strengthen the supporting plates. For example, the application number is CN201910776118.6 The patent of published a kind of car door sill assembly of steel structure. [0003] At present, the new sill components such as sills, pallets, and reinforcing ribs are all made of sheet metal. Since all components are manufactured by the manufacturer, the probability of error is small, and compared with the method of purchasing some components from other manufacturers and reassembling, The cost is relatively small, so it is more and more popular with elevator manufacturers. However, in the manufacturing process, at lea...
